Sibling rivalries

Has to be the saddest form of rivalry because you're beefing with someone who has the purest of love and intentions for you. Anyway, I'm a second born na one of my new year resolutions was mending what seems to be a broken bond with my older brother (less than 2 years btw). So Friday tulienda kulewa and it started out well coz a mutual friend of ours had his gf coming over and she pulled up with her friends. 3 girls 3 men ratio ilikuwa imekubali so good vibes zikaanza. Tell me why this ngga all of a sudden anaanza kudrag story zangu personal and mind you he's not providing solutions, ngga's just airing out my dirty linen in public. After a few minutes hao madem walisense vibe iko off then they dipped. Hapo ndio full blown argument zikaanza. So this ngga is trying to argue na story hazimhusu (I mean he's just my brother si ati ananilipia fee of any kind). Anyway, that shit has been on my mind tangu weekend. So today I decided to adress it tukiwa sober nikamwambia "being brothers doesn't necessarily make us friends, we don't have to do this hanging out shit" akamumble something then nikamwambia "ukinikujia ivo tena tutapigana fr". For context I'm way taller and more muscular than him despite being younger. Anyway any advice? Juu tukiendelea hivi tutakuwa enstranged
